Transients in Color Television

A color television system transmits three independent signals, each of which specifies one of the three co-ordinates that determine the location of the reproduced color in a three-dimensional color space. When a color transient occurs, each of these signals responds in a different manner determined by the characteristics of its own channel. The system response may be characterized by the resulting path along which the reproduced color point moves through the color space from its initial to its final location. The shape of such color transient paths as determined by the individual transient responses of the three channels is analyzed, and the subjective appearance of different transient-path shapes is discussed.
